Ethylene oxide does not impair sterilized articles and is highly penetrable. Most articles that are not suitable for sterilization by conventional methods can be sterilized and sterilized with ethylene oxide. It can be used for sterilization of metal products, endoscopes, dialyzers and disposable medical devices, industrial sterilization of various fabrics and plastic products, and articles of infectious diseases (such as chemical fiber fabrics, leather, paper, documents, Oil painting) disinfection treatment.
Ethylene oxide can not be used for disinfection of food. After hydrolysis of ethylene oxide, it can produce a small amount of toxic glycol, and it can not be used for blood sterilization. It can cause cell lysis, complement inactivation and thrombin destruction. .
With the development of the medical industry, more and more new medical devices are put into use, and the problem that comes with them is that many medical devices are not resistant to high temperatures and high humidity. In recent years, the hazards caused by nosocomial infections have been widely concerned. In the past, some types of catheters, ventilator tubes, and laparoscopic surgical instruments that are not resistant to high pressure and humidity are commonly used in chemical disinfectants or gas fumigation. Sterilize.
Since most of the chemical disinfectant aqueous solution is volatile and the concentration is unstable, the disinfection effect is extremely uncertain, and the device needs to be washed with a large amount of physiological saline before use, otherwise the residual liquid is irritating to the body and easily causes toxic side effects. Gas fumigation The formaldehyde gas currently used is toxic and is prohibited from being used for disinfection of articles directly in contact with human body.
Compared with hydrogen peroxide plasma, ozone, peracetic acid, formaldehyde, ethylene oxide, etc. are all low temperature sterilizing agents. The ethylene oxide has strong penetrating power, wide spectrum of sterilization, light damage to articles, and long shelf life of articles. The sterilization effect is certain and the cost is low. Therefore, ethylene oxide is an ideal low-temperature sterilizing agent to date, and it is widely used in medical and industrial sterilization, and can be applied to precision instruments and optical instruments. Sterilization of electronic equipment, various catheters and plastic products.
